W-104: GXcommunication warning
W-104: GXcommunication warning
Good morning ladies and gentlemen
I have an issue with my EV no screen charger not connecting to cerbo gx device
Is the ev ns connect to my wifi or is it supposed to connect to the cerbo gx directly
The pdf instructions are a little vague
Does the programing need to be AP or STATION
Also where it states “Check GX device IP address and VRM portal lD configuration” (is the gx device the ev charger)
Please see pics

Much appreciated , thankyou

Hello @Bpower .
EVCS and GX should be on the same WiFi network. Usually, EVCS and GX are connected to the home router.
Also, please double-check that:

  1. ModbusTCP service is enabled on GX under Settings ->Services->ModbusTCP
  2. EVCS activated on GX under Settings → Modbus TCP/UDP devices → Discovered devices
